What is the Fallback Subject Line?
Your Fallback Subject Line is used if the system doesn't know enough about an Audience Member, preventing them from getting a personalized subject line in their News Digest.
If you would like to set a Fallback Subject Line for your non-personalized Subscribers, go to Settings > News Digest > scroll down to the Miscellaneous Sending Controls section > add a Fallback Subject Line > click Save (located in the upper right hand corner of your screen).
